Instantly convert CMYK to RGB

R = 255 × (1-C) × (1-K)
G = 255 × (1-M) × (1-K)
B = 255 × (1-Y) × (1-K)

K = 1-max(R', G', B')
C = (1-R'-K) / (1-K)
M = (1-G'-K) / (1-K)
Y = (1-B'-K) / (1-K)

My bad, though the current Goodie may still need tiny modifications (you have to write % to convert from CMYK) or keep the <MODE>(VAL, VAL, VAL) syntax. But you are absolutely right.

Was just looking for this! Also hoping to see conversions from HEX to RGB or CMYK. For example, "#00a9d to RGB" would result in "rgb(0,169,210)".

Very handy for designers going back and forth between web and print!
